["No match"](https://licensedseptic.com/septic-license-lookup/#no-match) does not mean unlicensed. Names and phone numbers on a state list often differ from the ones in ads. Ask for the license number. **Before you call.** Ask for the total price and which fees can be added: digging up or opening the lid, extra sludge, a trip charge. Ask if they pump every compartment through the main lid and check the baffles. Ask for the license or permit number, then compare it to the one on this page. If the pumper says you need a repair, get three written quotes before you agree. ## In Williston ### [Capex Oilfield Services Inc](https://licensedseptic.com/septic-pumping/north-dakota/williston/capex-oilfield-services-inc/) Williston, ND ✓ North Dakota license NDSP07406 [Call (701) 572-4908](tel:+17015724908) ### [MonDak Portables LLC](https://licensedseptic.com/septic-pumping/north-dakota/williston/mondak-portables-llc/) Williston, ND ✓ North Dakota license NDSP007303 [Call (701) 570-5444](tel:+17015705444) ### [Nova Oilfield Services, Inc.](https://licensedseptic.com/septic-pumping/north-dakota/williston/nova-oilfield-services-inc/) Williston, ND ✓ North Dakota license NDSP007292 [Call (701) 580-8251](tel:+17015808251) ### [Seidel Septic LLC](https://licensedseptic.com/septic-pumping/north-dakota/williston/seidel-septic-llc/) Williston, ND ✓ North Dakota license NDSP07400 [Call (701) 770-2123](tel:+17017702123) ### [Stallion Infrastructure - Williston](https://licensedseptic.com/septic-pumping/north-dakota/williston/stallion-infrastructure-williston/) Williston, ND ✓ North Dakota license NDSP007342 [Call (701) 774-3824](tel:+17017743824) ### Vac U Jet 5979 136th Ave NW, Williston, ND 58801 No match on the North Dakota list [Call (701) 572-0826](tel:+17015720826) [Website](http://vacujetseptic.com/) Order: companies matched to a state list first, then listings with more complete data (phone, website, street address), then by name.
